Damn, I missed the sale on the 25cr callys!
But I agree Alosso, some much better value balls are available. Personally I have a mixture of Srixons, slow meter Callys and even some Max balls. Depends how my reactions and reflexes are (I play a few practice holes usually before I start).
I like the analogy of the ball cost as the green fee, and for the few cents it costs, is pretty cheap entertainment.
The OP has been using starters balls, and once again if you are finding the meter too fast, revert to the starters and play a few practice rounds. When you revert back to a good ball the meter will seem slow.
